What is an Audio Extractor? The Complete Guide
From magnetic tape and razor blades to one-click MP3 extraction — the full story of how to pull sound out of video
So What Exactly is an Audio Extractor?
Audio extraction is a simple concept, but incredibly useful. An Audio extractor is a tool that pulls the sound track out of a video and saves it as an audio file. Let say you have a music video? Extract the song. You have a recorder lecture video, this tool helps you to extract just voice from that video. You want to grab dialogues from a movie clip? use audio extractor.
I started building an audio extractor tool, when I need to crack an interview but I had only video recordings and I need to extract recording audios. Most of the online tools require subscriptions and online payments. So I decided to build an audio extractor.
Once the audio file is extracted, you can save it in different formats. Save as MP3 for everyday use, WAV format is for studio-quality editing, FLAC if you're an audiophile, or AAC for Apple devices.
The History of Audio Extraction — From Magnetic Tape to Milliseconds
In the early era, when movies started having sounds, the audio was recorded separately on magnetic films and then run parallel to the picture film. If you wanted to have an audio, then you had to play the audio reel and then record it onto another device. At that time, there was no "Extraction"— just re-recording.
The invention of VCRs made audio recording possible but this was still a terrible task. To extract audio, you'd connect your VCR's audio output to a cassette deck and press record on both machines. Then you'd play the video and just pray nobody walked through the room. Because one simple vibration could ruin the whole recording.
Apple's QuickTime new update QuickTime 2.0 introduced the ability to "Export" audio from video files. For the first time in history you could extrcat audio from videos without analog degradation. But the major issue was that you need a powerful computer to handle this. A 30-second audio extraction could take five minutes.
When Napster was launched, everyone suddenly start demanding MP3 files. In this way audio extractors became essential tools. Programs like DVD audio extractor and Audacity gained huge popularity in that days. People started extracting music from concerts, movie soundtracks and the music videos. In this way a new term "Audio Extrcation" gained people attrcation.
YouTube also plays an important role in demand of audio extraction. As people wanted to save audio from YouTube videos as MP3 files. In this way hundreds of online YouTube to MP3 converters are popped up at browsers. But all of them are worked same.
Modern browsers can now decode video and extrcat audio files locally without uploading files to any servers. Modern browsers use WebAudio API and other technologies to extract audio. When you extract audio, your video doesn't leave your device.
How Does Audio Extraction Actually Work Under the Hood?
Let me explain this without making your head hurt. I'll keep it simple and practical.
Now-a-days every one is concern about data privacy. So when you select a video file, browser reads it from your hard drive. You file is not uploaded to anywhere.
Video files are like containers, which hold both picture data and sound data at the same time. When we try to extract audio from videos , the browser looks inside the container and pulls out sound data only, while pictures data part is temporarily ignored. This extraction process happens almost instantly because browser knows exactly where the audio data is stored.
Most of the videos has compressed audio to save space. Browsers have to UnZip or uncompress this audio into raw sound, so that your computer can easily understand. This process is called decoding. There are different compression methods like — AAC, MP3, AC-3, etc. Modern browsers can decode nearly all of them automatically.
After decoding the audio file to raw format, The browser takes the raw audio and re-compress it as an MP3 file. But if you want WAV? it saves the raw audio without compression. It depends upon your suggestion.
Finally the last step, which is a bit simple. Your browser offers the newly created audio file as download. Whenever you click "Save" the extracted file will automatically save to your downloads folder.
Which Audio Format Should You Choose? (Real Talk)
This tool gives you six format options. Here's when to actually use each one based on real-world needs.
MP3 files are best for listening, uploading to social media, sharing. It is considered as a universal audio file format. Every speaker, every car, every phone, every computer can plays MP3. File sizes are small. Quality is good enough for 99% of people. This is what I use 95% of the time.
WAV files are uncompressed files. They preserve every single detail from from the original videos. WAV file sizes are huge. Normally a 3-minute song as MP3 might be of 3MB. But as MAV, it could be 30MB. WAV files are best for: Professional editing, archival, when you need perfect audio quality.
Best for: Apple devices, streaming, podcasting. AAC sounds slightly better than MP3 but at the same bitrate. Apple music and YouTube both uses AAC. If you are creating content for Apple platforms, you must use AAC. But note — some older Android phones have issues with AAC.
Best for: music collectors, archival, Audiophiles. FLAC compresses audio without losing any quality (lossless compression). FLAC is like ZIP for audio, smaller than WAV but still has perfect quality. But the major issue is that, Not every device or software plays FLAC. If you are found of listening music then MP3 is best for you. BUt if are thinking about to build a music library then go with FLAC.
OGG files are often used in Open-source softwares, web developement and gaming. OGG sounds are most popular in gaming world. OGG quality is coparable to listeners. But regular users won't find OGG files very frequently.
Best for: iPads, iTunes, iPhones. M4A is Apple's version of AAC. If you are extracting audio files to run or add it to your iTunes library or put it on an iPhone, you must choose M4A format. It works seamlessly with Apple's ecosystem. For everything else, MP3 or AAC are more universal.
What Does "Audio Enhancement" Actually Do?
There is a toggle "Audio Enhancement" in this tool. Let me tell you clearly what is this toggle for in this tool.
This is used to quiet background sounds to get more clear and cleaner results. Background sounds like traffic outside your window, air conditioner noise, the hum of a computer fan. Any sound below a specific threshold gets silenced.
Have you faced a situation where sound coming from speaker suddenly gets loud, then get quiet, then gets loud again. Normalization is the process to analyze the entire audio track and adjust the track volume to be consistent throughout. The result is that you get a consistent volume which boost content.
When should you use "Audio Enhancement" ? If your video was recorded in a noisy area (Cafe, outdoors, parties, offices, events) or has inconsistent volume, turn it on. If your audio is already stable and has a clean audio, you don't need to use it.Turning on enhancement takes some extra seconds but for spoken content like interviews, lectures or vlogs, this featue usually worth it.
Who Actually Uses Audio Extractors? (Real Examples)
After watching people use this tool for years, here are the most common real-world use cases I've seen.
Podcasters and interviewers record their interviews but only need audio for podcast distribution. They extract audio from video as MP3, add into/outro music and publish. One recording session gives both video for YouTube and audio for podcast platforms.
They record video lessons and extract audio from these videos for students to download and listen while exercising. All this because audio-only versions are smaller in size and are more portable than full video files.
People in these fields need to store their favourite singers or musicians soundtracks, songs and playlists. But if these files are in video format then they have to store data in huge sizes, so they extract audio from soundtracks, songs, favourite playlists and save these audio files as MP3 format. Which is more easy to store and access whenever they needed.
Some regular people or learners download videos in their target language, extract audio and listen these audio files repeatedly for immense practise. Much easier to replay audio files again and again then to keep opening video files.
What I've Learned From Extracting Thousands of Audio Files
After years of extracting audio from every type of video imaginable, here is what actually matters when you extracting audio from videos.
- 192 kbps MP3 is the sweet spot.If you want to extract audio in MP3 format then keep audio quality to 192 kbps, which is the perfect balance. If you lower than that you'll hear compression artifacts. And if you higher audio quality than that (256 or 320) the file size will increase dramatically.
- Use enhancement for spoken word, skip it for music. Use noise gate and volume normalization, if your audio or sounds have spoken words like interviews, lectures, outdoors. You will get better and smoother results. For music, they can kill the dynamics.
- Always trim before extracting if you only need part of the video. Its totally useless to extract a total 30 minute audio but you need only 5 minute audio from middle of the uploaded video. So first of all notice the part you need to extract, trim that part using our "Video Trimmer" and then extract only the required part audio.
- Check the waveform before downloading. The waveform is a feature which catches problems in your extracted audio you might miss by just listening. This waveform visualization shows where the audio is quiet, where it is loud, and if there is any weired silence.
- Batch processing is a lifesaver for repetitive work. If you extract audio from multiple video on daily basis, then batch mode is only for you. Set your settings once, add all your files, and let it run.
- Keep the original video until you've checked the extracted audio. I learned a lesson from my experience, don't delete the source video before verify. Extracted audio sometimes has issues, sync problems, clipping and weird sounds.
